Criminal B's car is deactivated, so he starts shooting and kills Cop A and Cop B. Then instantly surrenders, only to receive a 75% decreased jail time for murdering two cops and running from the cops. I think you have to wait a few seconds before doing /sur after moving and in that time cops can arrest/tase you easily. I believe tasing someone when they've surrendered and giving the criminal the time what he would have originally gotten without surrendering is just a bug, because this makes zero sense lol
